The SmallRig Pro Mobile Cage for iPhone 11 Pro (17mm Threaded Lens Version) - Model 2775 is a premium, form-fitting aluminum protective housing engineered to transform the iPhone 11 Pro into a professional mobile filmmaking and vlogging platform.

Unlike standard plastic phone cases, the 2775 is an architectural metal exoskeleton. It protects the phone chassis from drops while acting as a rigid structural hub for attaching cinema glass, external microphones, LED video lights, and multi-axis handles.

Key Engineering and Structural Features

  • Anodized Aluminum Construction with Shock-Absorbing Pads: The entire cage is CNC-machined from high-strength aluminum alloy, protecting the smartphone from high-impact damage. The interior cavity is lined with soft, custom-molded rubber and EVA padding to absorb shock and prevent the cage from scratching the phone's glass and steel exterior.

  • 17mm Threaded Optical Lens Plate: Built directly into the rear camera cutout of the cage is a mathematically aligned 17mm threaded lens mount baseline. This enables mobile cinematographers to screw premium anamorphic, wide-angle, or macro lenses (such as those from Ulanzi, Sandmarc, or Kase) directly over the iPhone’s native lenses with zero frame play or alignment drift.

  • Quick-In / Quick-Out Dual-Lock System: The cage uses a toolless, quick-acting pop-lock sliding door mechanism. Filmmakers can press the mechanical latch, slide the top door open, insert the phone, and click it shut in under two seconds.

  • Dual Cold Shoe & Cheese-Plate Mounting Array: The frame is a comprehensive mobile rigging layout. It includes two built-in cold shoe mounts (one on the top horizontal frame, one on the left vertical side) alongside multiple 1/4"-20 threaded holes. These points allow you to mount mini shotguns, wireless audio receivers, or LED panels without adding bulky accessory brackets.

  • Ergonomic Handheld Grip Expansion: The side and top 1/4"-20 hole layouts match standard handle dimensions. This allows operators to bolt on a top handle (such as SmallRig SKU 1984) or dual side handles (such as SmallRig SKU 2424) for rock-solid, multi-handed tracking shots and stable mobile panning.

💡 Operational Mobile Production Tips for the 2775 Cage

The Lens Alignment and Weight Distribution Rule: Attaching high-quality 17mm threaded cinema lenses or heavy anamorphic glass over the camera module creates an off-center weight distribution, throwing the phone's balance toward the upper right. If you mount the cage straight onto a standard compact desktop tripod using a single center screw, the setup will feel top-heavy and tilt easily. To stabilize your frame, attach a SmallRig Lightweight Side Handle (such as SKU HSS2424) to the opposite vertical rail. This grip lets you brace the rig with your hand to smooth out walking vibrations and reduce wrist fatigue.

  • Protecting the iPhone Screen Assembly: While the thick aluminum walls of the 2775 cage shield the sides and back of your iPhone 11 Pro, the front screen remains completely exposed to protect the touch interface. Always pair the cage with a high-quality tempered glass screen protector. Ensure the screen protector is installed perfectly straight; if it extends over the curved glass edges of the phone, the tight rubber padding inside the cage can squeeze the edge, causing the screen protector to bubble or lift away from the display.

  • Bypassing Audio Cable Stress Points: When rigging an external microphone (like a Rode VideoMicro) to the top cold shoe of the cage, you must use an Apple Lightning-to-3.5mm headphone adapter to pipe the audio into the phone. Because mobile setups are subject to sudden movements, tether the adapter cable to the side of the 2775 cage using a small hook-and-loop cable strap. Securing the line stops the adapter from bouncing around, preventing popping noises in your audio track and keeping the Lightning port from wearing out over time.

Durable and Rugged
Color: Black
I've had it for a few weeks now. It was a replacement I bought after buying several vinyl type covers. This one is a good gauge of plastic and rubber. The rubber seems pretty strong and it protects the iPad well on the corners and back. The back is mostly covered except for the Apple logo in the center. In addition to protecting the corners and also protects the camera lens as the rubber after insulation is a little bit higher than the lens so when you put this down, it's not going to scratch the lens. It has a pen slot, which I like and plenty of room to grip the device if I'm carrying it from place a place or when I'm using it, I can grip the edge and not touch the screen. One of the things I would've liked included is a screen protector, but nothing covers the screen. I also miss the folio type cover because the screen will gather dust now. But, Apple screens are fairly durable so I'm not too worried about breaking it. It was easy to install. It came in as it came in a couple of pieces that you just pressed together. All the controls are obvious as they are under the rubber, but they look like keys. One more thing I might bring up is the charging port. It's easy to get to even though it's a little deep. On my iPad the touch sensor is on the on off button and it is a little harder to do than if I didn't have any case on it, but that is to be expected. It also has an easel that unfolds from the back if you want to sit it up, but I don't use it for watching anything since I have a real TV set. So far I like it and I'm glad I bought this as I don't think it's going to wear out as quickly from me handling it as the others did. The value was good as long as it lasts.
